美松齿小蠹是一种主要分布于北美的危险性林木害虫,随着我国与北美国家木材贸易往来的日益密切,该虫传入我国的风险也逐渐升高。为了更有效地实现美松齿小蠹的风险防控,本研究采用DIVA-GIS的BIOCLIM生态位模型对美松齿小蠹在我国的适生性进行了预测。结果表明,美松齿小蠹在我国的较适宜生存地区主要分布在辽宁、山东、陕西、山西、河南、四川、湖北、云南、西藏、河北等省份的局部地区。应当在这些地区强化检疫措施,以防美松齿小蠹的传入和扩散。 Pinus tritonus is a dangerous pest mainly distributed in North America. With the increasingly close trade between China and North American countries, the risk of the insect entering our country is gradually increasing. In order to achieve more effective control of the risk of Beauveria coggygons, the BIOCLIM niche model of DIVA-GIS was used to predict the fitness of Beauveria bassiana in China. The results showed that Pinus densiflora is mainly distributed in some suitable provinces in Liaoning Province, Shandong, Shanxi, Shanxi, Henan, Sichuan, Hubei, Yunnan, Tibet and Hebei. Quarantine measures should be strengthened in these areas to prevent the introduction and spread of Pinaceae.
